TRi-PRO is the king of water care that handles chlorination, pH balance and maintains the correct Active Chlorine Levels. The TRi system ushers in a new era in water care with a series of three ‘modules’ that can be configured to suit every pool owner’s individual needs. The TRi sets itself apart with ‘inbuilt intelligence’ – computer controlled smarts that monitor pool chemistry and warn you if there is a problem.
